Microsoft Outlook 2010 error message:
The server you are connected to is using a security certificate that cannot be verified. The target principal name is incorrect.
If you see this message, it's usually caused by a mismatch in enabling SSL and the port number as entered in your Outlook account settings.
You'll want to make sure that your incoming and outgoing server port settings match those below:
|Username||Your full email address|
|Password||Your password (Same for Incoming and Outgoing server)|
|Password Encryption / SPA||Not supported|
|IMAP Port (SSL)||993|
|POP3 Port (SSL)||995|
|SMTP Port (SSL)||465|
